Abstract

A display apparatus including a display panel, a touch panel, a data driver, a common voltage noise predictor and a touch position detector. The display panel includes a plurality of data lines and a plurality of pixels. The pixels are electrically connected to the data lines, respectively. The touch panel is configured to output a first touch signal based on a touch event. The data driver is configured to output a data voltage to the data line based on a data signal. The common voltage noise predictor is configured to output a common voltage noise compensating signal based on the data signal. The touch position detector is configured to detect a touch position based on the common voltage noise compensating signal and the first touch signal.

Description

[0001]This application claims priority from and benefit under 35 U.S.C. §119(a) of Korean Patent Application No. 10-2014-0012136, filed on Feb. 3, 2014, which is herein incorporated by reference for all purposes as if fully set forth herein.BACKGROUND[0002]1. Field[0003]Exemplary embodiments of the present inventive concept relate to a display apparatus and a method for driving the display apparatus. More particularly, exemplary embodiments of the present inventive concept relate to a display apparatus with increased touch recognition rates and a method for driving the display apparatus.[0004]2. Discussion of the Background[0005]A display apparatus may include a touch panel which senses a touch event that occurred on a screen, and outputs a touch signal. As the thickness of the display apparatus decreases, a noise defect of the display apparatus may increase.[0006]A ripple noise of a common voltage, which is generated according to a physical characteristic of the display panel and a...
